Is Atoms Mask washable?

Yes, the Atoms Mask is washable. After 50 washes, the inner copper layer loses its effectiveness in its ability to actively destroy germs and particles. It can still be used as a regular cloth mask, but will not have extra antimicrobial benefits. To wash your mask, Atoms recommends placing the mask in a bowl or basin, adding a small amount of your favorite soap or detergent and water, and then using your fingers to work suds throughout the mask. After this is done, the mask should be rinsed thoroughly, pat or wrung dry of excess water, and then hung up to air dry.
